0B47745

High-Density 3.5-Inch Enterprise SAS Nearline HDD featuring EAMR media technology with the 0B47745

The 0B47745 is a 16TB WD Ultrastar DC HC555 3.5-inch internal enterprise HDD designed for SAS 12Gb/s backplanes in rack servers, JBOD shelves, and scale-out storage nodes where predictable latency and sustained sequential throughput matter more than flash-level IOPS. In multi-drive environments, the 0B47745 leverages RV sensors and a triple stage actuator to maintain head stability under vibration, supporting consistent performance in dense chassis and high-bay storage enclosures.

Architecturally, the 0B47745 aligns with modern storage stacks that depend on controller-managed queues and end-to-end data integrity, including SAS multipath and enterprise RAID/HBA topologies. With 512MB cache and 7200RPM operation, the 0B47745 fits capacity tiering for nearline datasets, backup targets, and object storage where large blocks dominate. The 512e format enables broad OS and hypervisor compatibility while retaining 4Kn-aligned media efficiencies, and SED support allows hardware-based data-at-rest protection within established key management processes.

Why Choose the 0B47745?

The 0B47745 delivers an efficient density-to-bay ratio for capacity-heavy pools, reducing rack footprint and simplifying growth planning for software-defined storage and archival tiers. Its enterprise duty-cycle design, high MTBF profile, and vibration-aware mechanics support scalable deployments where many drives operate concurrently and rebuild windows must remain manageable under sustained load.

WD engineers the Ultrastar platform for 24x7 data center operation with tight manufacturing tolerances, telemetry-aware reliability, and compatibility expectations aligned to standard SAS enterprise ecosystems. This design focus supports repeatable integration across server generations and storage enclosures without operational surprises.

Key Applications:

Nearline bulk storage tiers
Backup and archival repositories
Ceph and object storage nodes
Scale-out HDD JBOD expansion
Enterprise RAID arrays for virtualisation

At Happyware - Server Hardware you benefit from non-binding offers tailored to your storage architecture and rollout timeline, plus extended warranty options up to 6 years to protect long-lifecycle capacity investments based on the 0B47745.
